The text is aligned by its bounding box (the rectangular box that surrounds the ink rectangle). The order of operations is rotation then alignment. Basically, the text is centered at your (x, y) location, rotated around this point, and then aligned according to the bounding box of the rotated text. So if you specify left, bottom alignment, the bottom left of the bounding box of the rotated text will be at the (x, y) coordinate of the text. But a picture is worth a thousand words! .. image:: /gallery/text_labels_and_annotations/images/sphx_glr_text_rotation_001.png :class: sphx-glr-single-img .. code-block:: default import matplotlib.pyplot as plt import numpy as np def addtext(ax, props): ax.text(0.5, 0.5, 'text 0', props, rotation=0) ax.text(1.5, 0.5, 'text 45', props, rotation=45) ax.text(2.5, 0.5, 'text 135', props, rotation=135) ax.text(3.5, 0.5, 'text 225', props, rotation=225) ax.text(4.5, 0.5, 'text -45', props, rotation=-45) for x in range(0, 5): ax.scatter(x + 0.5, 0.5, color='r', alpha=0.5) ax.set_yticks([0, .5, 1]) ax.set_xticks(np.arange(0, 5.1, 0.5)) ax.set_xlim(0, 5) ax.grid(True) # the text bounding box bbox = {'fc': '0.8', 'pad': 0} fig, axs = plt.subplots(2, 1, sharex=True) addtext(axs[0], {'ha': 'center', 'va': 'center', 'bbox': bbox}) axs[0].set_ylabel('center / center') addtext(axs[1], {'ha': 'left', 'va': 'bottom', 'bbox': bbox}) axs[1].set_ylabel('left / bottom') plt.show() .. _sphx_glr_download_gallery_text_labels_and_annotations_text_rotation.py: .. only :: html .. container:: sphx-glr-footer :class: sphx-glr-footer-example .. container:: sphx-glr-download sphx-glr-download-python :download:`Download Python source code: text_rotation.py ` .. container:: sphx-glr-download sphx-glr-download-jupyter :download:`Download Jupyter notebook: text_rotation.ipynb ` .. only:: html .. rst-class:: sphx-glr-signature Keywords: matplotlib code example, codex, python plot, pyplot `Gallery generated by Sphinx-Gallery `_
